Multi-objective Bayesian optimization of rigid and flexible nozzles for energy-efficient pulsed jet propulsion
Paras Singh, Yukesh Karki, Victor Hernandez +3
The biomechanics of pulsed-jet propulsion in aquatic animals, including squids and jellyfish, provide valuable insights into energy-efficient locomotion. In these organisms, flexib…

Computational and reduced-order modelling of elastic wave-driven impulse enhancement in pulsed jets through passively flexible nozzles
Paras Singh, Daehyun Choi, Saad Bhamla +1
Elastic wave propagation and energy exchange in passively deforming cylindrical nozzles are investigated through three-dimensional, two-way fluid-structure interaction simulations.…

Squid-inspired soft superpropulsion
Daehyun Choi, Paras Singh, Ian Bergerson +12
Squid span four orders of magnitude in size yet rely on pulsed jets. We show that the funnel (siphon) is a compliant nozzle whose dilation and recoil lag mantle contraction, storin…
